SPINNING APPARATUS FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 767,263, dated August 9, 1904.

Application filed June 15, 1903.

To all whom, it may concern.-

Be it known that 'I', HENRY F. Co'rTLn, of Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Spinning Apparatus for Spinning-Frames, of which the following is a Specification.

This invention has for its object to enable a spinning-ring to be automatically adjusted to the spindle as to its concentricity therewith and also to enable the upper edge of the ring or the ring-race on which the traveler moves to be automatically leveled in compensation for anyirregularities or deviations of the ringsupport from a true horizontal position.

The invention consists in the improvements which I will now proceed to describe and claim.

Figs. 13 to 17, inclusive, represent other modifications hereinafter referred to. Fig. 18 represents a perspective view of a portion of a sheet-metal ring-rail formed as a ring-support in accordance with my invention. Fig. 19 represents a perspective view of a cast-metal ring-rail also formed as a ring-support. Fig. 20 represents a sectional view of the rail, shown in Serial No. 161,442. (No model.)

Fig. 19 and a ring engaged therewith. Fig. 21 represents a sectional view of a ring and a bash engaged therewith, the base being formed to engage different rings. Fig. 22 represents a ring and its weighted base formed as one part.

The same characters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a support or holder for a spinning-ring a, said holder having rigid confining members adapted to permit a limited upward or tipping movement or inclination of any part of the ring and a limited longitudinal or edgewise movement of the ring. In the preferred embodiments of my invention, hereinafter described, the said rigid confining members cooperate with complemental confining members afiixed to the ring in permitting limited rotary movements of the ring, while preventing more than a fractional part of a complete rotation.

A ring supported in accordance with my invention is adapted to tip in any desired direction without being lifted or separated at any point from its seat. The ring is therefore adapted to be leveled or made horizontal by the action of the traveler, so that if the ringrail happens to be slightly out of level, as is often the case, the ring will be caused by the traveler to assume a level position on its seat without being actually lifted from its seat at any point, and therefore without imposing an uneven strain on the yarn.

In each of the preferred embodiments of my invention provision is made for weighting the base or lower portion of the ring to steady it and prevent abrupt fluctuations or jerky movements, such as would be liable to occur with an ordinary reversible ring, the lower portion of which is of substantially the same weight as the upper or traveler-guiding portion.

In the embodiment of my invention shown in Figs. 1 to 7, inclusive, the holder is composed of a ring 5, preferably of sheet metal, having a flat under surface adapted to rest on the upper surface of the ring-rail and provided with slots 5 to engage attaching-screws, whereby the holder may be rigidly secured to the ring-rail. The inner margin of the ringshaped holder Z) constitutes a seat for a base portion or annular weight a, which is afiiXed to the lower flange or race of the ring a and moves in all directions with the ring. lower portion of the base (0 presents a frustoconical or tapering face 2, the lower portion of which bears upon the inner edge of the holder .7). Said inner edge constitutes a seat on which the base is free to tip in any direction required to level the base and ring, the face 2 remaining in contact with all parts of the seat without being raised therefrom by any tipping movement permitted by the described construction. The base and holder are provided with complemental confining parts, which permit limited vertical and edgewise movements of the base and ring and also limited rotary movements of said parts. Said members comprise slotted ears Z), projecting inwardly from the inner edge of the holder and bent upwardly, as shown in Figs. 3 and I, and fingers a formed on the inner surface of the base (4 said fingers projecting into the slots of the ears 7/. The lower edge of the base a" is provided with recesses a? to accommodate the ears 6'. Said ears may be formed integral with the holder Z), as shown in Fig. e which shows the ears before they are bent upwardly.

In Figs. 8 and 9 I show a construction in which the frusto-conical or inclined face corresponding to the face 2 is an inclined flange 3, formed on the holder 5. In this case the lower edge of the base a bears loosely on the inclined flange 3-, so that the base and ring are free to have the same movements that are provided for by the construction shown in Figs. 1 to 7 The confining members are ears 6, formed on the holder 6, said ears projecting upwardly and outwardly, their outwardly projecting portions engaging seg mental grooves a", formed in the inner surface of the base ad. The rotary movements of the base and ring are limited by the ends of the grooves 64.

In Fig. 10 I show a construction similar to that shown in Figs. 8 and 9, the chief difference being as follows: Outwardly-inclined ears are formed on the upper edge of the inclined flange 3, said ears entering inclined slots a in the base a.

In Figs. 11 and 12 the holder 6 is flat and its inner edge forms a seat, as in the construction first described, the base a having an inclined face 2 resting loosely on said seat. The base is provided with inclined slots a which receive inwardly-inclined ears If, formed on the holder 6.

In Figs. 13 and 14 I show the holder 6 provided with ears 6 on its outer margin. Said ears are bent backwardly, so that they everhang the base e. The base is \l-shaped in cross-section, its upper edge bearing on the upper side of the bottom flange of the ring a The and being cut at intervals to form cars a, bearing on the under side of said flange, the base being thus rigidly secured to the ring. The cars 7/ are narrower than the slots (0 formed by the inward bending of the ears (1,, and stand at such height that there is room between their under sides and the said tongues for a slight vertical movement of the base and ring, the ears 7) permittingaliinited horizontal and limited gyratory movement of the base.

In each of the above-described embodiments of my invention the weighted base (a is preferably secured detachably to the ring, so that after the upper race has been worn by the traveler the ring may be inverted. In the construction shown in Figs. 1 to 12 the base a is formed to be sprung upon the lower flange of the ring, the base being cut through at one side, as shown at 5, and of resilient construction, so that it will exert a strong frictional hold on the ring, the base being also provided with a ring-engaging shoulder a In Figs. 16 and 17 I show a holder composed of a ring (7, preferably of sheet metal, having radial incisions extending from its inner edge partly across to its outer edge, said incisions forming tongues (Z d, which are bent upwardly, and tongues (Z (Z which are bent downwardly. The tongues (Z collectively form a seat for the base of the ring a, which seat is practically frusto-conical in form and cooperates with the lower flange of the ring (a in permitting a tipping movement of the ring. The ears (Z overhang the said seat and the lower flange of the ring. Sufiicient space is formed between the ears (Z (Z to permit the ring to move horizontally and vertically to a limited extent. In this embodiment of my invention the ring is not weighted and is adapted to rotate.

The ring-holder may form an integral part of a sheet-metal ring-rail 1', as shown in Fig.

'18, in which I show the ring-rail provided with a circular orifice r, the margin of which forms a seat for the frusto-conical face 2 on the base (f, the rail also having slotted ears r correspending to the ears 6'. Either of the other forms of holder above described may be made integral with a sheet-metal ring-rail.

In Figs. 19 and 20 I show a cast-metal ring rail having an orifice r and a series of bent fingers 9*, which engage an annular groove 0," in the base (4 In Fig. 2]. the base a is provided on its inner surface with a series of shoulders a of different diameters, whereby it is enabled to engage rings of different sizes, the base being adapted to be sprung onto the ring.

I do not limit myself to a base made as a separate part detachably connected with the ring, it being obvious that when a reversible ring is not desired the ring and base may be formed as a single part, as shown in Fig. 22, in which (4 represents the weighted base.

It will be seen that my invention enables ITO the ring to properly adjust itself to the spindle in such manner as to prevent any irregularity in the pull of the yarn on the traveler an d ring and automatically compensate for the vibration of the spindle. An even product is thus assured, and the wear of the traveler is materially reduced, thereby allowing the frame to be run at a higher speed.
